I would like to have your thoughts regarding the well-equipped radar stations (Anton L 479 bunkers) which were built by the Germans on various strategic positions located in Brittany, France. Like at Cap Frehel ; Rennes [Saint-Jacques-de-la-Lande] ; Pointe-du-Raz ; La Baule [Escoublac].

It seems to me that the L-479 bunkers were fitted with “Mammut Fu MO 52 Caesar” (…among other devices) a system which detects planes in formation about 300kms away, some of them (?) with Seeburg tables. These devices were supposed to be utilised for the Nachtjagd control (…maybe Tagjagd – as for Rennes I believe) as an air-defence warning system. Right? But, there have never been any Nachtjagd unit stationed in the West part of France and the Bomber Command air raids intended to Germany (…or other occupied countries) did not pass through this airspace. At night, Allied planes have not been bothered during their air-raids over Brittany...apart from German anti-aircraft defences. So, why to have built all these well-equipped stations? These devices/stations were perhaps overstated for only a day-time use, no? For only a question of standardisation? As far as I know, these stations sites has been very few attacked by the Allied (...later in 1944 perhaps).

As a non-specialist, those are all of the questions that I am asking myself; so gentlemen, could you please give me your thoughts or perhaps some clarification on that?
